Overview
Hebei wastewater treatment plant serves Zhaoxian County, Hebei, China, with a population of 100,000. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Shita Village, Zhaozhou Town, Zhaoxian County, Shijiazhuang City, Hebei Province, China. It serves a population of approximately 100,000 people, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent is discharged into local waterways that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The Hai River system supports agricultural irrigation and industrial water use in the North China Plain, making effective treatment critical for downstream water quality and ecosystem health.
Environmental context
The Hebei plant discharges into the Hai River basin, which flows through the North China Plain and empties into the Bohai Sea. This watershed is heavily utilized for agriculture and industry, and the Bohai Sea is a semi-enclosed water body with limited tidal exchange, making it vulnerable to nutrient pollution. Effective treatment at this plant helps reduce nitrogen and phosphorus loads that could otherwise contribute to eutrophication in coastal waters.
